Summary

Android smart-phones have different security policy from the conventional cell-phones.
Conventional cell-phones are secured by carrier and hardware maker.

To avoid such risks, android shows list of functions that the app uses. And ask user whether install the app or not.
However, messages android shows are not easy to understand. Almost users install apps without understanding the messages.

  • com.airpush.
  • com.Leadbolt.
  • com.appenda.
  • com.iac.notification.
  • com.hairstyles.teens
